Swept-source OCT system based on a Polarization-dependent Semiconductor Optical Amplifier-enabled Fourier Domain Mode Locked Laser

摘要：

　　We demonstrate a swept-source OCT system based on a polorization-dependent semiconductor optical amplifier (SOA)-enabled Fourier Domain Mode Locked laser (FDML).The broad bandwidth and high saturation power of the semiconductor optical amplifier enables single semiconductor optical amplifier operation with enough bandwidth and output power.The FDML generates ~32mW output power at 45kHz sweep rates,with a tuning range of 115 nm centered at 1326 nm.Using the SOA-enabled FDML laser,~12.9μm axial resolution,9μm transverse spot size and 105dB sensitivity are achieved.OCT imaging of biological sample is also demonstrated.
